All of a sudden, rFactor 2 won't start.  It worked yesterday.  Today when I click on the image, it says it cannot find the config file.  I click OK as usual.  That window goes away and it says it is starting.  20 minutes later it still says the game is starting but of course it is not.  I have deleted all the games in Commander, let commander find all games again.  All my other games load properly.  rFactor 2 will not. What do I need to do to get it to actually start the game?
